The verdict

The Redwood Outdoors Alaskan is a 130-gallon heat-treated hemlock tub with a lid and steps that needs no power or plumbing. It's $2,700 on sale against a printed $2,999, plus freight shipping calculated at checkout. The catch is that cold water depends on ice, and Redwood decides whether to accept a return.

The trade-off

Without a chiller, cold water depends on ice, and Redwood doesn't say how much ice that takes or how cold the water gets.

About this price

Sale price. On Oct 24, 2026, Redwood's product page showed the Stained tub at $2,700 against a printed regular price of $2,999, marked "Sale". The page doesn't say when the sale ends. A banner also promotes early access to a Black Friday sale by phone, so the price may change. The page says shipping is calculated at checkout, and the tub travels by freight in a wooden crate to the curb. The price is before tax and shipping. Redwood sells a separate Alaskan All-In-One Cold Plunge with a built-in chiller at $6,999 for the Standard Model. A chiller isn't offered as an add-on on this tub's page.

A GOOD FIT FOR

You want a wood-clad ice tub for a yard or beside a sauna and have a pad or deck for about 1,334 lb.

You want a wood-clad ice tub for a yard or beside a sauna
A spot with a reinforced pad or deck that can carry about 1,334 lb
You'd rather start with ice and decide on a chiller later

THINK TWICE IF

You want cold water on demand without buying ice
A cold-winter yard where you won't drain the tub or keep it from freezing, since freeze damage isn't covered
You might want a refund, since Redwood approves returns case by case and the tub goes back in its crate
A deck or upper floor that can't carry about 1,334 lb

What still needs checking

How much ice a fill needs and how long the water stays cold
The lowest water temperature the tub reaches with ice
The insulation's rating and how well the lid holds the cold
Which diameter is the inside, since the page says 37 in and the FAQ says about 31 in
Whether the liner is molded acrylic or fiberglass
Freight cost, which Redwood calculates at checkout
Return freight cost and whether any restocking fee applies
The price and model of a chiller that fits this tub, since the page lists none
Whether the bromine and water balancing kits are back in stock
Whether the tub carries any certification, since the pages name none

Does the Redwood Outdoors Alaskan cold plunge tub come with a chiller?

No, the Alaskan Cold Plunge Tub is sold without a chiller, and you cool it with ice¹. Redwood’s spec table lists the chiller type as not included¹.

Redwood sells a separate Alaskan All-In-One Cold Plunge with a built-in chiller that it says reaches 37°F, at $6,999 for the Standard Model⁷. Redwood’s FAQ mentions chiller hoses for this tub, but the tub’s page doesn’t list a chiller to add^{1, 3}.

Dimensions	Redwood's product page lists the tub at 37 in in diameter and 40.5 in tall. Its FAQ says about 31 in across and about 40 in tall, and neither page says which figure is the inside. It holds up to 130 gallons and seats one person. The tub weighs 250 lb empty and 1,334 lb with water, per the product page. The FAQ rounds the filled weight to about 1,350 lb. The movable steps are 23.25 in wide, 21.25 in long and 25 in tall. The tub ships in a wooden crate 3 ft 2 in wide, 3 ft 4 in long and 3 ft 4 in tall.

The FAQ says a reflective insulation layer sits between the liner and the wood. The stained model comes with a clear linseed-oil primer that Redwood says protects the wood for about 12 months. The FAQ then suggests a marine-grade sealer for the tub, the steps and both sides of the lid. The manual says to reapply stain and seal every 1 to 2 years.

Before you buy

InstallationWithout a chiller, the tub needs no outlet or plumbing

Without a chiller, the tub needs no outlet or plumbing. Assembly takes three steps with the supplied parts. Screw the two handles onto the lid, take the steps out of the tub, and screw the drainpipe onto the bottom outlet. Redwood's manual asks for a strong, level foundation. That means a concrete pad at least 4 in thick with mesh, or a deck an architect or building engineer has checked for the weight. It advises against dirt or grass. The drain has a 3/4 in garden hose connection and works by gravity. The manual suggests a 1/4 HP submersible utility pump, around $60, to move the water farther. A freight truck delivers the crate to the curb by appointment, and someone has to be there to sign. The page's delivery estimate showed an order on Oct 23 shipping Nov 3, and Redwood calls delivery times estimates.

WarrantyOne year from delivery, per Redwood's warranty policy for cold plunge tubs

One year from delivery, per Redwood's warranty policy for cold plunge tubs. It covers defects in materials and workmanship for the original buyer. Redwood chooses between replacement parts, a replacement tub or a full or partial refund. Labor, installation and removal aren't covered, and Redwood pays reasonable shipping only on returns it authorizes. Freight damage, cosmetic blemishes and poor water maintenance are excluded. The tub must not be operated, stored or left filled at or below 32°F unless it's winterized, and freeze damage isn't covered. Claims go by email with proof of purchase and photos or video. Redwood's chillers are also covered for 1 year.

Returns30 days from delivery, and Redwood must approve the return in writing first

30 days from delivery, and Redwood must approve the return in writing first. Redwood decides whether to give a full refund, a partial refund or credit, less shipping and handling and other costs. The tub must come back disassembled, palletized and in its original wood crate. The policy doesn't say who pays return freight or name a restocking fee. An order with a cold plunge is held 7 days before processing. Canceling in that window is free, and after it the charge is 3.5% of the order. Damage has to be noted on the delivery paperwork and emailed to Redwood within 7 days.

Replacement parts & cost assumptions

Recorded recurring parts and refills:

Ice: price not stated. Without a chiller, the water gets cold from ice. Redwood doesn't say how much ice a fill takes or how long the water stays cold, so ice isn't priced. Its FAQ says to change the water after each session when you use ice and no sanitizer.
SpaGuard bromine water sanitizing kit: $249. Redwood lists the kit at $249, with tablets, shock, test strips and a floating dispenser. It says to use one tablet per 100 gallons and add shock weekly. Redwood's FAQ says the water may last about 7 days with bromine and no chiller. The manual says 7 to 10 days. The listing showed the kit unavailable on Oct 24, 2026, and no replacement schedule is given.
SpaGuard water balancing kit: $149. Redwood lists the kit at $149, with pH decreaser, alkalinity increaser, calcium hardness increaser and test strips. Redwood's FAQ says both kits are needed if you change the water infrequently. The listing showed it unavailable on Oct 24, 2026, and no replacement schedule is given.
Wood stain and sealer: price not stated. Redwood says the factory primer protects the wood for about 12 months, then suggests a marine-grade sealer. The manual says to reapply stain and seal every 1 to 2 years. Redwood doesn't sell or price a sealer on the tub's page.

Purchase is the $2,700 sale price on Oct 24, 2026, against a printed regular price of $2,999. A Black Friday early-access banner means the price may change. Shipping is calculated at checkout and isn't included.
Installation is unknown. Assembly uses the supplied parts, and no outlet or plumbing is needed without a chiller. Redwood asks for a pad at least 4 in thick or an engineered deck and doesn't price either.
Watts and hours are 0 because Redwood says the tub needs no electricity without a chiller. A chiller would add power use, and Redwood gives no chiller price for this tub.
Annual consumables are unknown. Ice is the main running cost, and Redwood gives no quantity. The bromine and water balancing kits list at $249 and $149 with no schedule, and the wood sealer is unpriced.
Other yearly costs are $0. The page lists no app, subscription or membership.

Evidence & sources.

Do cold plunges work? Our evidence review grades the research as Mixed. That grade is about the claim, not about this product.

Manufacturer claimThe price, sale, capacity, dimensions, weights, materials, drain, inclusions, warranty and return terms come from Redwood Outdoors' product page, manual, FAQ, warranty policy and shipping and returns policies, checked on Oct 24, 2026.^1–6 It's Redwood's own information, not independent testing of temperature holding, ice use or durability. The pages disagree in places. They give 37 in against about 31 in across, molded acrylic against fiberglass, 1,334 lb against about 1,350 lb filled, and a linseed-oil primer against a wood wax oil.
Manufacturer claimThe product page lists faster recovery, immune, mood and stress benefits of cold exposure. It cites no studies, certification or regulatory clearance for the tub.¹ These are Redwood's claims about cold exposure in general, not evidence about this tub. The manual's safety page names the Alaskan All-In-One and water up to 104°F, so it looks adapted from that product. It suggests starting at 59°F for 1 to 2 minutes. It also says to ask a doctor first if you have heart disease, blood pressure or circulation problems, or diabetes. Studies of cold-water immersion weren't reviewed here.
